Optical cords (patch cords) are intended for connecting different segments of optical communication lines to each other, as well as for connecting them to active network and testing and measuring equipment. Patch cords ensure high connection reliability and allow for quick reconnection if necessary. Optical connection cords are a segment of an optical cable terminated on both sides with identical connectors and are made of single-mode (yellow sheath) or multi-mode (orange sheath) fiber. Double cords have connector polarity markings, which allow determining the input and output sides of the light signal.
